<header>Max number of parallel deliveries to the same local recipient</header>

<center><tt>local_destination_concurrency_limit</tt></center>
<hr>

This parameter limits the number of parallel deliveries to the same local
recipient.

<p>

The default limit is taken from the
<a href=opt_default_destination_concurrency_limit>
<tt>default_destination_concurrency_limit</tt></a> parameter. Postfix documentation
recommends a low limit of 2, just in case someone has an expensive shell
command in a <tt>.forward</tt> file or in an alias (e.g., a mailing list
manager). You don't want to run lots of those.
